"I have joined a party that is committed to listening to the people of Queensland and clearly got feedback last weekend in Stafford," he said.

"I think it is vital to show support of a party that will do that."

Dr Davis said he wanted to help restore confidence and undo the damage caused to the hospital system by the LNP.

"To reverse the great decline in morale, over 1,500 doctors joining a union when they got the message that they were all expendable and could easily be replaced ... that was very poor judgment on behalf of the Government," he said.

She said she had been talking with Labor's former member Kate Jones about running in the electorate.

ALP state secretary Anthony Chisholm said today it was not yet known if Ms Jones would run for Labor in Ashgrove.

"The party process hasn't started in Ashgrove as yet, so I wouldn't expect Kate Jones to declare her hand prior to that, and as I said earlier, it'll be up the party members to decide," he said.

Davis' preselection as Labor candidate unlikely

Mr Chisholm said it was unlikely Dr Davis would get preselected to run for Labor for Mr Newman's seat in Brisbane.

"To run as a candidate you need six months' membership and nominations in Ashgrove will open very, very soon," he said.

"The practical reality of that - dealing with a hypothetical - even if Mr Davis was admitted to the party, he wouldn't have the requisite length of membership to contest.

"In regards to Ashgrove, an existing party member will be the Labor candidate for Ashgrove and that'll be up to branch members to choose who that is.

"We're confident we'll have a number of strong candidates who are interested in Ashgrove and the candidate will come from that field."

Mr Chisholm said Dr Davis' party membership application would not be considered until mid-August.

"That membership application would be treated along with the other hundreds of other members who have joined in the last month," he said.

"I can't pre-empt the decision of the administrative committee - that would be up to them.

"But obviously Mr Davis has spoken out about a number of issues that are important to the Labor Party, particularly on integrity and accountability, and the Newman Government winding back those reforms. He obviously is someone who doesn't align with the LNP Government on those matters.

"But any decision in regards to membership would be a matter for the admin committee."

Davis may make federal politics bid

Mr Chisholm would not comment on whether Labor's membership process meant Dr Davis could not be preselected to run for any other seat in the state for the party.

"We're not going to deal in hypotheticals," he said.

"Mr Davis' membership hasn't even been accepted at the moment and a lot of the preselections for south-east Queensland seats have taken place."

Dr Davis says he will consider federal politics if he is not chosen for a state seat with the ALP.

"It really doesn't matter where the opportunity presents, the whole picture needs to be addressed," he said.

"There is a great deal of overlap between both state and federal healthcare arrangements. I know that some people are talking of simplifying that."
